Install Lock Channels
Only wing (gauge wheel) lock cylinders need to be
installed for transport. The center is adequately
supported by the wing hooks and locks when folded.
For servicing, or to hold at lift when unfolded, also install
center section lift locks (see page 73)
Refer to Figure 20
8.
Remove lift cylinder transport lock channels from
their storage positions.

Place transport lock channels on lift cylinders
located on gauge wheels.
Activate Fold Solenoid Valves

10. Set Hydraulic Selector Marker/Fold switch to
“Fold”
. This opens the solenoid valves for tongue
lock, fold cylinders and caster arm cylinders.
Begin Folding
Crushing Hazard:
Keep all persons away from frame sections during lift and
lower. Area under row units is particularly dangerous. Sharp
coulter and opener blades descend with hundreds of pounds of
down-force.
11. Extend the fold cylinders and fold the planter until the
wing tubes are within a few feet (a meter or so) of the
tongue.
